HiFlo: HF562
Kymco: 1541A-KKC3-900
HiFlow is made by K&N and a very good OEM replacement part for 1/2 the price. After all, it's just a paper filter not too much can be made wrong. I do have a few of the OEM kymco ones in stock if you'd like to take them off our hands, don't see many Yager's in Portland so the filters just sit upstairs. Can do $12 each plus USPS, normally $16.95 each.
